Description

Technical Field

[0001] This invention relates to the field of winding machine technology, and in particular to a coil winding mechanism with a starting end bend. Background Technology

[0002] A coil typically refers to a toroidal winding of conductor. The most common coils are found in motors, inductors, transformers, and loop antennas. In the field of electrical component manufacturing, coil winding is a crucial technology, widely used in the production of transformers, inductors, motors, and various electromagnetic devices. The quality of the winding directly affects the electrical performance and mechanical stability of the coil, with the treatment of the starting and ending wires being particularly critical. Typically, the starting and ending wires of the coil are required to have regular, parallel bends at both ends of the coil, and the bent starting and ending wires must be perpendicular to the coil axis to facilitate subsequent insertion into circuit boards, soldering, or conforming to the conductor path of the mounting housing.

[0003] With the development of automation technology, automatic winding machines have gradually replaced manual operation, improving production efficiency and winding accuracy. In existing technologies, automatic winding machines typically guide enameled wire onto the coil frame using guide pins and possess basic functions such as wire cutting and clamping. However, significant shortcomings remain in the handling of the starting and ending wires, especially in the bending, fixing, and anti-loosening of these wires. For example, during the bending of the ending wire, since it remains connected to the coil body after the main body is completed, without effective pressure and guidance, the wire can easily loosen the wound coil, leading to inaccurate turn counts, uneven interlayer gaps, and reduced electrical performance consistency. Furthermore, existing technologies often use a swing arm or pneumatic fingers for unilateral bending after the starting and ending wires are cut, lacking precise positioning and support for the starting and ending wire sections. The bending is greatly affected by wire tension and springback. Summary of the Invention

[0004] In view of this, the present invention provides a coil winding mechanism with a starting and ending wire bending to solve the above-mentioned technical problems.

[0005] A coil winding mechanism with a bendable tail wire includes a frame, a first mold assembly mounted on the frame, a second mold assembly mounted on the frame, a guide pin assembly mounted on the frame, a drive assembly mounted on the frame, and a wire-blocking assembly mounted on the frame. The first mold assembly includes a first drive shaft movably mounted on the frame, a first mold plate mounted on the first drive shaft, and a first fixing seat mounted on the first mold plate. One end of the first drive shaft is connected to the drive assembly, and the other end is fitted with the first mold plate. The first fixing seat is inserted into the first mold plate and used to set the coil bobbin. The second mold assembly includes a second drive shaft movably mounted on the frame, a second mold plate mounted on the second drive shaft, a second fixing seat mounted on the second mold plate, and a guide pin assembly mounted on the second mold plate. The system includes a skeleton fixing assembly on the plate, a wire clamp assembly on the second mold plate, and at least one bending post on the second mold plate. One end of the second drive shaft is connected to the drive assembly, and the other end is provided with the second mold plate. The second mold plate has a mounting block. One end of the coil skeleton is inserted into the second fixing seat, and the other end of the coil skeleton is inserted into the first fixing seat. The skeleton fixing assembly is used to press down one end of the coil skeleton. The bending post is used as a bending support point for bending the wire. The guide needle assembly includes a first three-axis moving device and a guide needle disposed on the first three-axis moving device. During the winding process, the guide needle, driven by the first three-axis moving device, winds the wire around the bending post to complete the wire starting bend. After the winding is completed, the wire blocking assembly presses down the starting section of the tail wire. Subsequently, the guide needle continues to move to wind the tail wire around the bending post to complete the tail wire bend.

[0006] Furthermore, the coil winding mechanism for bending the tail wire also includes a wire cutting and clamping assembly mounted on the frame. The wire cutting and clamping assembly includes a second three-axis moving device and a wire cutting clamp mounted on the second three-axis moving device. The second three-axis moving device is used to drive the wire cutting clamp to move, thereby controlling the wire cutting clamp to clamp the wire and move it, so that the wire passing through the guide pin is sent to the starting clamp assembly to be clamped, thus completing the fixing of the starting wire, or cutting the tail wire at the guide pin after the tail wire is bent, thus completing the cutting of the tail wire.

[0007] Furthermore, the first mold assembly also includes a first connecting shaft inserted into the first fixed base and the first mold plate, and a first spring disposed between the first fixed base and the first mold plate. The first fixed base is provided with an oblong hole, the first connecting shaft passes through the oblong hole and its two ends are inserted into the first mold plate, and the first spring abuts between the first fixed base and the first mold plate, and pushes the first fixed base to move away from the first mold plate in a free state by its own elastic force.

[0008] Furthermore, the second fixing base is provided with two spaced-apart L-shaped limiting blocks, and one end of the coil frame is inserted between the limiting blocks and the second fixing base.

[0009] Furthermore, the skeleton fixing assembly includes a first movable rod movably inserted into the mounting block, a pressure block disposed at one end of the first movable rod, a first abutment block disposed at the other end of the first movable rod, and a second spring sleeved on the first movable rod. One end of the second spring abuts against the first abutment block, and the other end abuts against the mounting block. In a free state, the second spring pushes the first movable rod to move away from the mounting block by its own elastic force, while the pressure block disposed at one end of the first movable rod moves together, moving towards the limiting block and pressing one end of the coil skeleton.

[0010] Furthermore, a limiting groove is provided on one side of the pressure block, and the starting wire will extend into the coil frame along the limiting groove.

[0011] Furthermore, the wire clamp assembly includes a lower clamping block disposed on the mounting block, a second movable rod movably disposed on the lower clamping block, an upper clamping block disposed at one end of the second movable rod, a second abutting block disposed at the other end of the second movable rod, and a third spring sleeved on the second movable rod. The lower clamping block rotates together with the mounting block, the second movable rod movably passes through the lower clamping block, one end of the third spring abuts against the lower clamping block, and the other end abuts against the second abutting block. Through its own elastic force, the spring drives the upper clamping block to move towards the upper clamping block, so that the lower clamping block and the upper clamping block are tightly attached to each other to clamp the wire.

[0012] Furthermore, two bending posts are provided, including a starting line bending post and a tail line bending post, which are used to bend the starting line and the tail line, respectively.

[0013] Furthermore, the drive assembly includes a first rotating mechanism disposed on the frame, a second rotating mechanism disposed on the frame, a first axial moving mechanism disposed on the frame, and a second axial moving mechanism disposed on the frame.

[0014] Furthermore, the wire-blocking assembly includes a two-axis moving device and a wire-blocking block disposed on the two-axis moving device, the wire-blocking block being used to press down the starting section of the tail wire when bending the tail wire.

[0015] Compared with existing technologies, the coil winding mechanism for bending the starting and ending wires provided by this invention first securely clamps the starting end of the wire delivered by the wire cutter clamp through the starting clamp assembly, providing a stable starting point for winding. Then, the guide pin guides the wire around the starting bending post to complete the first 90° bend, precisely entering the winding area along the limiting groove on the pressure block, ensuring the starting segment is perpendicular to the skeleton axis. When processing the ending wire after winding, the wire stop block first presses down on the starting segment of the ending wire, effectively preventing the wound coil from loosening due to pulling. The guide pin then guides the ending wire around the ending bending post to complete the second 90° bend, ensuring that the ending and starting wires have an ideal parallel bending shape. The entire bending process of the starting and ending wires is completed automatically, greatly improving the bending quality and the overall stability of the coil. Attached Figure Description

Detailed Implementation

[0028] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0029] like Figures 1 to 11The diagram shown is a structural schematic of the coil winding mechanism for bending the starting and ending wires provided by the present invention. The coil winding mechanism for bending the starting and ending wires includes a frame 10, a first mold assembly 20 disposed on the frame 10, a second mold assembly 30 disposed on the frame 10, a guide pin assembly 40 disposed on the frame 10, a wire cutting and clamping assembly 50 disposed on the frame 10, a drive assembly 60 disposed on the frame 10, and a wire blocking assembly 70 disposed on the frame 10. It is conceivable that the coil winding mechanism for bending the starting and ending wires also includes other functional components, such as drive devices, connecting components, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0030] The frame 10 has a U-shaped structure and is used to support the above-mentioned functional modules. Therefore, the frame 10 is provided with a variety of functional structures, such as screws, bolts, through holes, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.

[0031] The first mold assembly 20 includes a first drive shaft 21 movably disposed on the frame 10, a first mold plate 22 disposed on the first drive shaft 21, a first fixing seat 23 disposed on the first mold plate 22, a first connecting shaft 24 inserted into the first fixing seat 23 and the first mold plate 22, and a first spring 25 disposed between the first fixing seat 23 and the first mold plate 22.

[0032] One end of the first drive shaft 21 is connected to the drive assembly 60, and the other end is provided with the first mold plate 22. The first drive shaft 21 can rotate and move axially under the drive of the drive assembly 60, thereby driving the first mold plate 22 and the first fixed seat 23 to rotate and move axially. How the axial movement is performed will be explained in detail below.

[0033] The first fixing seat 23 is inserted into the first mold plate 22 and is used to set the coil frame 100. The first fixing seat 23 is provided with an oblong hole 26. The first connecting shaft 24 passes through the oblong hole 26 and its two ends are inserted into the first mold plate 22, so that the first fixing seat 23 can move a certain distance along the oblong hole 26. The first spring 25 abuts between the first fixing seat 23 and the first mold plate 22, so that it pushes the first fixing seat 23 away from the first mold plate 22 in a free state by its own elastic force. When the first mold assembly 20 and the second mold assembly 30 are closed, the first fixing seat 23 is retracted by force and compresses the first spring 25, so that the first fixing seat 23 has a certain buffering capacity and avoids crushing the coil frame 100 when the mold is closed.

[0034] The second mold assembly 30 includes a second drive shaft 31 movably mounted on the frame 10, a second mold plate 32 mounted on the second drive shaft 31, a second fixing seat 33 mounted on the second mold plate 32, a skeleton fixing assembly 34 mounted on the second mold plate 32, a wire clamp assembly 35 mounted on the second mold plate 32, and at least one bending column 36 mounted on the second mold plate 32.

[0035] One end of the second drive shaft 31 is connected to the drive assembly 60, and the other end is provided with the second mold plate 32. The second drive shaft 31 can rotate and move axially under the drive of the drive assembly 60, which will be described in detail below.

[0036] The second mold plate 32 has a mounting block 38, which is used to set the various components of the second mold assembly 30 and to provide space for the bending of the starting and ending lines.

[0037] The second fixing seat 33 is disposed at one end of the mounting block 38 facing the first mold assembly 20. The second fixing seat 33 is provided with two spaced-apart L-shaped limiting blocks 39. One end of the coil frame 100 is inserted between the limiting block 39 and the second fixing seat 33, thereby being limited and pressed by the frame fixing assembly 34 to fix the other end of the coil frame.

[0038] The frame fixing assembly 34 includes a first movable rod 341 movably inserted into the mounting block 38, a pressure block 342 disposed at one end of the first movable rod 341, a first abutment block 343 disposed at the other end of the first movable rod 341, and a second spring 344 sleeved on the first movable rod 341. The pressure block 342 is located between the two limiting blocks 39. One end of the second spring 344 abuts against the first abutment block 343, and the other end abuts against the mounting block 38. In its free state, the spring 344 pushes the first movable rod 341 away from the mounting block 38 using its own elastic force. The pressure block 342 at one end of the first movable rod 341 moves along with it, moving towards the limiting block 39 and pressing down on one end of the coil frame 100. When unlocking is required, the first abutment block 343 is pushed, causing the first movable rod 341 to move the pressure block 342, thereby releasing the coil frame 100. A limiting groove 345 is provided on one side of the pressure block 342. The starting wire will extend into the coil frame 100 along the limiting groove 345 and then rotate to wind the wire. Therefore, the pressure block 342 is also used to guide and limit the starting wire.

[0039] The wire clamp assembly 35 includes a lower clamping block 351 disposed on the mounting block 38, a second movable rod 352 movably disposed on the lower clamping block 351, an upper clamping block 353 disposed at one end of the second movable rod 352, a second abutting block 354 disposed at the other end of the second movable rod 352, and a third spring 355 sleeved on the second movable rod 352. The lower clamping block 351 rotates together with the mounting block 38, and the second movable rod 352 movably passes through the lower clamping block 351. One end of the third spring 355 abuts against the lower clamping block 351, and the other end abuts against the second abutting block 354. Through its own elastic force, the spring drives the upper clamping block 353 to move towards the upper clamping block 353, thereby causing the lower clamping block 351 and the upper clamping block 353 to fit tightly together and clamp the wire.

[0040] The bending post 36 is used as a bending support point for bending the conductor. In this embodiment, two bending posts 36 are provided, including a starting bending post 361 and a tail bending post 362, which are used to bend the starting line and the tail line respectively. The specific winding process will be described in detail below.

[0041] The guide needle assembly 40 includes a first three-axis moving device 41 and a guide needle 42 disposed on the first three-axis moving device 41. The first three-axis moving device 41 is used to drive the guide needle 42 to move, thereby controlling the wire to continuously pass around the bending post 36, thus bending the starting and ending wire. The first three-axis moving device 41 should be prior art and will not be described in detail here.

[0042] The wire cutting and clamping assembly 50 includes a second three-axis moving device 51 and a wire cutting clamp 52 disposed on the second three-axis moving device 51.

[0043] The second three-axis moving device 51 is used to drive the wire cutting clamp 52 to move, thereby controlling the wire cutting clamp 52 to clamp the wire and move it, so that the wire passing through the guide pin 42 is sent to the wire starting clamp assembly 35 to be clamped, thus completing the fixing of the starting wire, or cutting the tail wire at the guide pin 42 after the winding is completed, thus completing the cutting of the tail wire.

[0044] The drive assembly 60 includes a first rotating mechanism 61 disposed on the frame 10, a second rotating mechanism 62 disposed on the frame 10, a first axial moving mechanism 63 disposed on the frame 10, and a second axial moving mechanism 64 disposed on the frame 10.

[0045] The first rotating mechanism 61 and the second rotating mechanism 62 are composed of a rotary motor, a belt, and bearings, etc. The output shaft of the rotary motor is connected to the second drive shaft 31 or the first drive shaft 21 via the belt, so that when the output shaft of the rotary motor rotates, it can drive the second drive shaft 31 or the first drive shaft 21 to rotate. The first rotating mechanism 61 drives the first drive shaft 21 to rotate, and the rotation of the first drive shaft 21 drives the first mold plate 22 and the first fixed base 23 to rotate, thereby realizing the rotation of the first mold assembly 20. The second rotating mechanism 62 drives the second drive shaft 31 to rotate, and the rotation of the second drive shaft 31 drives the second mold plate 32 to rotate, thereby realizing the rotation of the second mold assembly 30. The first axial movement mechanism 63 and the second axial movement mechanism 64 are composed of a lead screw moving device, a rotary motor, bearings, a coupling, and a connecting plate. The first axial movement mechanism 63 is used to drive the first drive shaft 21 to move axially, and the second axial movement mechanism 64 is used to drive the second drive shaft 31 to move axially, thereby controlling the first mold assembly 20 and the second mold assembly 30 to move closer or further apart to achieve mold closing or mold opening. The drive assembly 60 is similar to the synchronous transmission mechanism in a hollow coil winding machine disclosed in patent application number CN202321061739.4, therefore the drive assembly 60 should be considered prior art and will not be described further here.

[0046] The wire-blocking assembly 70 includes a two-axis moving device 71 and a wire-blocking block 72 disposed on the two-axis moving device 71. The wire-blocking block 72 is used to press down the starting section of the tail wire when bending the tail wire to prevent the winding portion of the coil from becoming loose. A detailed explanation will be given below in conjunction with the winding process.

[0047] During winding, the first mold assembly 20 and the second mold assembly 30 are first rotated by the drive assembly 60. Since the guide pin 42 is vertically positioned, the bending post 36 is positioned upwards to facilitate the movement of the guide pin 42 and avoid collision with the bending post 36. After the wire is pulled out from the external spool, it passes through the external tensioner and enters the guide pin 42. The wire cutting clamp assembly 50 clamps the wire passing through the guide pin 42 and moves it to the wire lifting clamp assembly 35 where it is clamped, thus completing the wire lifting and fixing. Then, the guide pin 42 drives the wire to pass around the wire lifting bending post 361 and then conforms to the limiting groove 345 on one side of the pressure block 342 into the area of ​​the coil frame 100, such as... Figure 9 As shown. Next, the driving assembly 60 drives the first mold assembly 20 and the second mold assembly 30 to rotate synchronously. Simultaneously, the guide pin 42 moves along the coil frame, causing the wire to wind around the coil frame 100 one turn at a time. After winding is complete, the first mold assembly 20 and the second mold assembly 30 rotate so that the bending post 36 is positioned to the side, i.e., towards the wire-blocking assembly 70, as shown. Figure 10 As shown. At this time, since the tail wire is still connected to the guide pin 42, if the guide pin 42 moves directly around the tail wire bending post 362 to bend the tail wire, it will cause the tail wire to transition at an angle with the coil body, which can easily lead to the coil body becoming loose. Furthermore, it cannot guarantee that the starting end of the tail wire is bent vertically, and the starting and ending wires are parallel to each other, affecting the winding quality. Therefore, the starting section of the tail wire is pressed down by the wire-blocking block 72, as shown. Figure 11 As shown, the guide pin 42 then moves, causing the tail wire to move horizontally. When it passes the tail wire bending post 362, it bends against it. Finally, the wire is heated and fixed by a hot air gun, and then the tail wire is cut by a wire cutter, completing the winding. The wire is enameled wire, and the outer enamel will melt and solidify after heating, which should be existing technology and will not be described in detail here. It is conceivable that the bending post 36 can also be set. Taking the starting bending post 361 as an example, the starting wire and the tail wire are bent from the upper and lower sides of the starting bending post 361, respectively.

[0048] Compared with the prior art, the coil winding mechanism for bending the starting and ending wires provided by the present invention first uses the starting wire clamp assembly 35 to firmly clamp the starting end of the wire delivered by the wire cutter clamp 52, providing a stable starting point for winding. Then, the guide pin 42 guides the wire around the starting wire bending post 361 to complete the first 90° bend, and precisely enters the winding area along the limiting groove 345 on the pressure block 342, ensuring that the starting segment is perpendicular to the skeleton axis. When processing the ending wire after winding, the wire stop block 72 first presses down on the starting segment of the ending wire, effectively preventing the wound coil from loosening due to pulling. The guide pin 42 then guides the ending wire around the ending wire bending post 362 to complete the second 90° bend, ensuring that the ending wire and the starting wire have an ideal parallel bending shape. The entire bending process of the starting and ending wires is completed automatically, greatly improving the bending quality and the overall stability of the coil.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
